4 Claims.

A further object of the invention is to provide a stencil with a pressure adhesive backing which positions, holds, and protects inner or projecting portions so that the backing can be stripped or removed therefrom without dislodging or dislocating the inner or projecting portions.

A still further object of the invention is to provide a new and improved method of stenciling in which an adhesive stencil with inner or projecting portions are connected by attaching parts which are removable before paint or color is applied so that definite and complete characters are formed without interrupted or broken lines therein.

Other and further objects of the invention will appear in the specification and will be apparent from the accompanying drawing in which,

Fig. 1 shows a stencil in accordance with this invention with connected inner or projecting portions and a removable adhesively applied protecting back:

Fig. 2 shows the stencil applied to a surface with the protecting back removed, and also with the attaching parts for the inner or projecting portions removed ready for the application ofbe broken or displaced in applying the stencil,

it is highly desirable to provide means not only for protecting the stencil itself before it isused, but also to protect the stencil and the parts thereof and to hold the parts in place while the stencil is being applied. It is likewise desirable, in many applications, that complete letters or characters are formed as a result of the stencil without broken lines or connections which tend to obscure the characters or to make them indefinite.

If color is applied by means of an air brush, it is necessary that the stencil and all portions of it are held tightly against the surface to be stenciled and to prevent the color from bleeding or running into any place where it is not intended. By providing the stencil and the inner or projecting portions thereof with a pressure adhesive, there is no danger that thin edges of the stencil or inner or projecting portions thereof will be blown up or dislocated by an air brush or dislodged by a brush when color is applied to the stencil.

The present invention overcomes all of these objections by providing a cut stencil having a protective adhesive backing removable therefrom, the stencil and thebacking both having removable attaching parts extending to the inner or projecting portions of the characters or illustrations of the stencil so that the backing may be stripped from the stencil itself without dis- 1 lodging, tearing or disfiguring the stencil, the removable attaching parts holding the inner or projecting portions of the characters in correct place and position so that by simply removing the attaching parts before color is applied, a complete and definite character is produced in the stencil itself which is correctly reproduced by painting or coloring applied in the ordinary way to the stencil.

Referring now more particularly to the drawing, a stencil sheet 5 of any suitable material such aspaper is coated at the back with a pressure sensitive adhesive 6, usually having a rubber base which will not injure a surface to which it is applied and to this is attached a protective cover sheet I of glassine, Holland cloth, and the like, which will adhere closely to the adhesive coating, but may be readily peeled and removed therefrom to prepare the stencil for use.

The stencil characters are cut through the sheet 5 and the cover sheet I and comprise inner parts such as an oval center 8 of a zero, an angular center 9 of a numeral 4, and circular portions III of a numeral 8 as well as projections drom different figures, illustrations or characters such as projections II and I! of a letter "S." These inner and projecting portions are liable to be bent, broken off, dislodged or dislocated unless particular care is taken to hold them properly in place, both before the stencil is used and while it is being applied for use.

The inner and projecting portions are therefore supported and positioned in the stencil by one or more connecting parts or ties l3 or It located relatively at one side of the inner or proing back cover I may be removed from the stencil in one direction of movement, usually from that side at which the said projections are attached,.

so that in stripping these pieces apart, the inner or projecting portions will not be dislocated.

After the protecting cover sheet is removed, the stencil is,applied to any suitable surface II. and by suitable pressure at the outside of the stencil, all parts and portions thereof will adhere closely to the surface. The removable parts or ties II and N are then disconnected at the ends I! thereof by means of a sharp knife or other cutting implement making the letters or characters definite and complete without any connecting bars or projections. The inner or projecting portions of the characters or other illustrations are pressed tightly against the surface it to which they are applied and remain in their proper position because of the pressure adhesive.

Color is then applied to the stencil as show in Fig. 2 either by an air brush or a regular paint brush, and because of the adhesive at the back of the stencil, the paint will not run or disflgure the stencil character. After the paint has dried, the outer and inner portions of the stencil are removed therefrom, leaving the characters or illustrations definite, complete and outstanding as shown in Fig.- 3.

The method of applying and usingthe stencil is thus completely described and will be readily understood. Although letters and numerals only are shown, other illustrations and designs may be stenciled in the same manner. Such stencils are intended to be used only once and then thrown away, but since they are relatively inexpensive, and are ready for immediate use, the application 2. A flexible adhesive stencil with an adhesive backing and a non-adhesive protecting cover sheet therefor, characters cut through the stencil and backing sheet and having ties connecting the exterior outlines of certain of the characters with interior isolated portions within the stencil characters, one of the ties for each isolated portion being located generally on the same side of all of the characters and some of the isolated portions having a positioning tie extending to an opposite side of the character whereby the cover sheet may be stripped from the stencil in a direction of numbers and other designating characters is greatly facilitated andspeeded without loss of any time for pointing up or finishing the letters after the stenciling operation is complete.

I claim:

1. A flexible adhesive stencil with an adhesive stripped from the stencil in a direction such that the cover sheet is removed first from those sides of the characters having the tie portions.

such that the cover sheet is removed first from the sides of the characters for which all of the isolated portions have ties, and all of the ties being adapted to hold the isolated portions in portion for applying the stencil to a surface to be stenciled.

3. A flexible adhesive stencil with an adhesive backing and a 4 non-adhesive protecting cover sheet therefor, characters cut through the stencil and backing sheet and having ties connecting the exterior outlines of certain of the characters with' interior isolated or semi-isolated portions within the stencil characters, the said ties being located generally on the same side of all of the characters, whereby the cover sheet may be stripped from the stencil in a direction such that the cover sheet is removed first from the sides of the characters having the tie portions, the ties holding the isolated and semi-isolated portions in position for application to a surface to be stenciled, and the ties being removable after application of the stencil to a surface to expose the entire face of the character.

4. The method of stenciling which comprises cutting characters through an adhesively back flexible sheet having a non-adhesive cover sheet applied thereto, connecting the interior isolated or semi-isolated portions within the characters with ties located generally on the same relative side of all of the characters, stripping the cover sheet from the adhesive stencil sheet in a direction such that the cover sheet is removed first from the sides of the characters having the tie portions, applying the flexible sheet to a surface to be stenciled, positioning the isolated or semiisolated portions by means of said ties, removing the ties only and leaving the isolated or semiisolated portions in proper character positions, applying color material to the stencil, removing the adhesive sheet with any partially isolatedportions, and removing the isolated portions.
